- Provided signed and sealed drawings, per the Connecticut Digital Projects Development Manual, showing staging plans and construction sequence to be used when replacing the existing equalizing strands and ground lines.
- When issues with the original staging plans occurred, Garg provided staging loads and recommendations based on a modified construction sequence as needed.
